Before, I gave TPM and AotC no regard whatsoever, and ROTS a general approval. However, I just finished a full SW marathon with some friends, many of whom had not seen any of the movies before. I substituted the MagnoliaFan prequels, and as a result, for the first time the Saga actually seemed to flow together- the plot made sense, the dialogue was decent, and the characters were a little less wooden. Even the big revelation in ESB still worked, because we knew Luke had no idea. This retained the emotion. I would have added in Ady's edit, but I'm still working on getting a copy. I know this sort of breaches edit threads, but for those who despise the prequels, the MagFan edits are the way to go.
And on an on-topic note, I can't wait to get my copy of this and watch it. :D
